      Question

      The number of present boys to girls is in the ratio 2:1.

      If 15 girls are absent and they form 25% of the total class, and no boy is absent, then find the number of boys in the class.
      A 28 Correct Answer Incorrect Answer
      B 25 Correct Answer Incorrect Answer
      C 30 Correct Answer Incorrect Answer
      D 27 Correct Answer Incorrect Answer
      E 33 Correct Answer Incorrect Answer

      Solution

      Total number of students = 15/0.25 = 60
      Number of students who are present = 60 – 15 = 45
      Therefore, number of boys in the class = 45 × 2/3 = 30
